Jeep Wrangler JK Rubicon 2 & 4 Door 5" Flex Arm Kit
Trailmaster's 5" Flex Arm Kit was engineered by Jeep enthusiasts with sportsman and rock crawlers in mind. The kit uses new front and rear coil springs, standard quick disconnect sway bar links and DOT approved braided steel, kevlar lined brake lines for front and rear. Trailmaster's .156 walled DOM tube replacement upper and lower control arms come with a flex joint for maximum articulation. Replacement front and rear track bars with heim joint ends are also included for proper geometry and bind free movement. SSV shocks round out the kit. New front and rear driveshafts are recommended. The 5" kit will easily accommodate 35" tall tires.

5" Flex Arm Kit

The JK family uses 22 different coil springs, each with a slightly different rate dictated by how the JK is equipped. New Superlift front / rear coils provide the lift. The largest jump in spring rate is from the 2 to 4-door model. Lift height can vary slightly (plus / minus up to 3/8") depending on your factory spring rate.

As the JK is raised, track bar angle increases and when lift height exceeds 2", bar length becomes an issue. Bar bind causes the chassis and axle to continuously "tug" against each other resulting in uneven ride height (side-to-side) chassis / frame misalignment and "roll and yaw". Front correction is accomplished via a new adjustable track bar. This route is preferred, as opposed to using a relocation bracket, since the bar's arc-of-travel must remain in-sync with the drag links arc-of-travel or steering wheel "kick" will result. A relocation bracket is used on the rear axle since there are no steering geometry issues.

The stock JK has no provisions for front caster angle realignment, which is required at this lift height, so Superlift provides new alignment cams. Compression travel is controlled via new urethane stops while new shocks improve control and restore full extension travel. The lift system also includes longer sway bar links with factory style, greasable tie-rod type upper ends, front / rear brake hose relocation brackets and emergency brake cable brackets ... nothing is left unattended.

Rockrunner Swivel Links for
2 and 4-Door Models including Rubicon

Coax the remaining twist out of your JK. The Rockrunner design has many advantages over other types of replacement links. The most common competitor's links are one-piece units with some type of pivoting eye bushing (like a Heim joint). Superlift's primary advantages are: a longer service life, quiet operation, less vibration and shock load transmitted from axle to chassis, and link length is adjustable so driveline and steering alignment can be dialed in. Links feature factory type steel encased rubber bushings at the frame ends for durability, flexibility and quiet operation, and high density greasable Urethane bushings at the axle ends for improved control.
